Pick a PDF in the app
Install Lyraboo from Google Play, tap + and choose a PDF from your phone — Downloads, Google Drive, wherever the file picker reaches. EPUB and TXT work the same way.
Android app
PDF to Audiobook App for Android
Lyraboo turns a PDF you own into a real audiobook — chapters, a proper player, and a different AI voice for every character. Free to start; the first chapter plays in about two minutes.
From PDF to audiobook in the app
No website uploads, no exporting to other formats first — for text-based PDFs it just works.
The app builds the audiobook
It splits the book into chapters, separates narration from dialogue and gives every character their own voice. Nothing to configure.
Listen like any audiobook
The first chapter is ready in about 1–2 minutes. Change speed, lock the screen and keep listening, pick up where you stopped — the next chapters generate in the background.
What the app gives you that a PDF reader doesn’t
- A full cast, not one robot voice. The AI works out who is speaking and casts a distinct voice for each character, so dialogue in a novel stays easy to follow. More on how that works: multi-voice audiobooks.
- A real audiobook player. Chapters, playback speed, background playback with lock-screen controls, and it remembers where you stopped.
- Read along when you want to. The text on screen follows the voice, which helps with study material or when you are reading in a language you are still learning.
- Your PDFs, EPUBs and TXT files — plus a built-in library of 1,000+ public-domain classics in English if you just want to try it.
App or online PDF-to-MP3 converter?
Most results for “PDF to audiobook” are websites that turn a file into an MP3 with one synthetic voice. That is the right tool when you need a file. Lyraboo is the other kind: an Android app you actually listen in. You do not get a file to carry around, but you get an audiobook — chapters, a player, and voices that change with the speaker — which is what makes a 400-page novel bearable to listen to. Every kind of tool is sorted by job in PDF to speech converters, and the apps are compared side by side in the best apps to turn a PDF into an audiobook.
It matters most for books that will never get an official audiobook: indie novels sold as PDFs, translated fiction, web novels, older titles. A studio recording costs thousands of dollars and will never happen for them; generating one costs a fraction of a single audiobook’s price.
Which PDFs work best
Any PDF with selectable text converts. If you have a choice, EPUB is the cleaner format for fiction because its chapters are explicit — see EPUB to audiobook. Scans without a text layer cannot be narrated. English books sound best; Spanish, Portuguese, French, German, Italian and Russian are in beta. New to the idea? Start with the guide: how to turn a PDF into an audiobook.
Why listeners choose Lyraboo
The things people notice in the first chapter — and the reasons they stay.
Every character gets their own voice
Lyraboo’s AI finds every character in the book and casts a distinct voice for each — automatically, for every book. You always know who is speaking, and dialogue sounds like a real conversation instead of one narrator doing all the parts. Most reading and text-to-speech apps use one voice for everything.
The text follows along, like lyrics
Under the player, the book scrolls with the voice the way song lyrics do in Spotify: words light up as they are spoken, each line shows who says it, and tapping any word jumps there.
A player that feels like a music app
Chapters, speed from 0.25× to 3×, background playback with lock-screen controls, and it picks up exactly where you stopped.
Upload, and you are listening in minutes
Pick an EPUB, PDF or TXT and there is nothing to set up: the first chapter is ready in about one to two minutes, and the rest generate while you listen.
Any book you have, not just a catalogue
Novels, fanfiction and web-serial exports, indie ebooks, study PDFs — plus over 1,000 English classics already in the app.
Fair on cost
One free hour of listening every month, no card needed. Hours are spent once per chapter — replaying is always free.
Frequently Asked Questions
Is there a free PDF to audiobook app?
Lyraboo is free to install, and every account gets one hour of listening each month — no card required. That is enough to hear whole chapters of your own PDF with the full voice cast before deciding whether to pay for more.
Can I download the audiobook as an MP3?
No. Lyraboo is a listening app, not a file converter: the audiobook plays inside the app and needs an internet connection. If what you need is an MP3 file to copy somewhere else, an online PDF-to-MP3 converter is the better tool. What you get here instead is chapters, a real player and a different voice for every character — and replaying a chapter you already generated never costs hours again.
Do scanned PDFs work?
Only if the PDF has real text in it — if you can select and copy a sentence, it will work. A scan that is just photos of pages has nothing to read, and the app will tell you so rather than narrate garbage. Run it through an OCR tool first, or use an EPUB or text-based copy of the same book.
Which languages can it read?
Lyraboo sounds best with English books. Spanish, Portuguese, French, German, Italian and Russian books can be narrated too, as a beta — the app works out the book’s language on its own. The app interface itself is in English.
What about big PDFs — a whole novel or textbook?
That is the normal case. Audio generates chapter by chapter in the background while you listen. Fiction gets the full multi-voice cast; non-fiction simply reads in the narrator’s voice.
Is there an iPhone app?
Not yet — Lyraboo is Android-only for now. iOS is on the roadmap.
